After many years of absurd problems with the BA app I've decided to do a review, as BA never seem to do anything about it. The app is absolutely appalling, the worst I've ever used. It is full of bugs, constantly crashes at key moments, regularly behaves in a completely random manner, unable to locate data then able to locate it, then losing it again... and twice in the last couple of months has failed to recognise my seat change, instead allocating the boarding pass with the pre-assigned seat despite me changing it. It then offers no option to go back and correct the error, you have to call customer service to change your seat. This means long waits on the phone to get it sorted, complete and utter waste of time. It repeatedly fails to recognise bookings, meaning you have to enter your booking reference to locate a booking that you made on the App and that should be automatically stored there (though in recent months this seems to happen less often, it used to be all the time). It also doesn't allocate the mobile boarding pass at the point of check in, instead producing a full page telling you that you need to go to 'my flights ' (which doesn't exist, it's My Bookings) to find it. Last time it took me 5 goes to get My Flights to take me to Get My Boarding Pass, as it was skipping to showing just the remaining bookings not yet checked in. Rather than having this pointless pop up at check in, why not just take the user straight to the boarding pass so it is all done and saved in one step like most other apps? Rubbish UI, British Airways you need new software engineers.
Overall it's unbelievable that they are so incompetent as to not be able to have a properly functioning app. The last time the customer service were extremely helpful and quick to change it, but one should not even have to call for such a matter. on top of that, recently there have been numerous problems with seats that don't function as they should, other cabin problems (recently on a long haul flight an overhead locker that kept opening noisily by itself, constantly waking us up all night, and that was Premium Economy) and more than half the time the flights are late. BA need to sort themselves out and try to return to pre-covid quality, and fix their absolutely terrible software systems.
Thanks also BA for removing all the women's lavatories in the Heathrow lounges; now women have no pleasant, private space in which to sort themselves out before/after flights, and instead have to remain in the cubicle which others may be waiting to use (and where a bunch of men have used the toilet, always nice) meaning others wait, and we wash our faces/do make up etc right beside a toilet. A lot of lost looking elderly women wandering about looking for the Ladies, last time I was at Heathrow T5. Great move, thanks BA, really respectful of what your female customers need. You could've kept the Ladies and simply installed some additional 'Gender Neutral' cubicles, but no, you need to remove a service we have all valued for many years. At least give us back a room in which we can freshen up.
In other respects the airline has merits, but after two years of really bad service I can see it's become a pattern hence this review. Sort it out, BA.

Do not book a flight with British Airways!! The system does not allow self service to re book. I spent over 45 minutes on the phone with an agent to be given one alternate flight and then be told that she could not provide additional flights because her shift would be ending. She then told me that she was not able to transfer me to anybody else either because there was nobody available and got off the phone because her shift ended. I will have to spend thousands of dollars to book a whole extra flight with a different airline since I am not able to get ahold of someone who can help. Outrageous.

Best Airline We Travell to London Love it. Always book British Airway next time Love it every thing .Every thing is excellent Crew etc.

Worst Airline I have EVER taken. Very little leg room, I'm 5'1 and I was squished. They made me miss my connecting flight due to unclear delays, landed in London at 8:30AM and was stuck there until 5:30PM. The airline provided a joke of 10 pounds to hold me over until my flight to Glasgow. They wasted a full day of my holiday with this nightmare. Do yourself a favor and fly with a different company.

Terrible customer service from several onboard flight attendants especially Keira Campbell!
I recently flew with British airways for the first time to fly back home to Jamaica. I never imagined such appalling customer service would be provided by a proclaimed top airline company. I pre-ordered a gluten free meal because of my gluten intolerance (celiac) this was not provided on the flight. Instead I was provided with fruits and a gluten free bread for a ten hour flight with no apologies! I also have an intolerance to tap water and I was feeling nauseous so thought some ginger / lemon tea may help. I asked the flight attendant Keira Campbell if I could check whether the water they use to make the tea is properly boiled. Her response was rude stating “she is not going to put her hand in it to find out is she”. I didn’t reply to this comment but instead went to ask another cabin crew who explained it is only brewed and because I have an intolerance if the chlorine in the water is not properly boiled off then it was best to avoid this. I requested the flight attendants name and informed the cabin manager I would make a complaint. When I arrived in Jamaica and was leaving the flight I overheard Keira Campbell and another blonde older female flight attendant talking about me as I walked by, stating “who this one”? Again I ignored the remarks and said nothing so as to not ruin my holiday experience. When I arrived back in the UK I placed a complaint through the BA services, however I was surprised that they had apparently closed the case without any email confirmation, correspondence or apologies. When you try to update the complaint it only allows claims request updates. I have flown with many airline services before as I am a frequent traveller, BA airways was by far the worst! I will only be flying with Tui to Jamaica going forward and my best advice to you is avoid this airline at all costs. They have no respect for customers who are the reason for their success. Flight attendants have attitudes lacking basic communication skills, empathy and care with no reflection / remorse. Avoid this airline especially if you have a special requirements in terms of diet religion communication!
